To all whom t may concern.'

Be it known thatwe, LOUIS BECKER, a citizen of the United States of America, residing in New York, in the borough of Manhattan, county and State of New York, and KARL HEINE, a citizen of the German Empire, residing in New York, in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Scarf-Pin AFasteners, of which the following is a specification.

|llhis invention relates to scarf-pin fasteners, and has for its object to provide an improved device of this kind which may be readily manufactured and which is eiiicient in operation.

The invention is shown in the `drawing hereto annexed, and will be more fully described hereinafter and finally pointed out in the claim.

In the drawing, Figure 1 is a perspective view of a fastener embodying the invention, showing the same applied to a scarf-pin,

Fig. 2 is a vertical longitudinal section thereof, on a larger scale, Fig. 3 is a vertical section on line 3*-3 of Fig. 2, Fig.- l is a hori- Zontal section on line 4 4 of Fig. 2, and Fig. 5 is a horizontal section on line 5-5 of Fig. 2.

Similar characters of reference indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, and mo-re particularly to Fig. 1, the scarf-pin 10 has applied thereto the fastener 11 having the manipulating member 31.

Referring more particularly to Figs. 2 and 3, which show our improved fastener in greater detail, the fastener 11 is composed of a guiding member 15 which hasV a longitudinal groove 16 running throughoutits length and adapted to receive the pin V10, and to guide the pin 10 during its move ment within the fastener. The guiding member 15 has at one end thereof a projection 17, which has a slot 18 through which a rod 19 is adapted to pass. The member 15 with its projection 17 is surrounded by a shell 20 which has at one end a turned-over portion 21, and at its other end a turnedover portion 22. Intermediate the member 15 and the turned-over portion 22, a circular plate 23 with a central opening 24 is placed,

said plate havingalso an eccentric opening 25 to permit the rod 19 to pass therethrough. i

The shell 2O is provided at its upper end with an inclined portion 26, and the member 15 is provided with a tapering portion 27 to conform to the inclination of this portion 26. This member 15, however, has a part thereof cut out, namely, all that part above the extension 17 and the guide-channel 16, and inwardly of the shell 20, whereby an openA space is left within the shell. This Y open space is providedto enable the opera-` tion of the rod 19 with the roller 30 at the end thereof. This rod 19 is provided at one i when the latter is in the guide-channel 16,

and serves to lock the pin -tightly in the guide-channel by having the roller 30 press on the pin 10, by reason of the spring 34. forcing the roller 30 upwardly, whereby a wedge action is produced between the inclined surface 26 and the pin 10, and pressing the latter against the member 15.

We have shown one embodiment of our invention, but it is clear that changes may be made therein without departing from the spirit of the invention as defined in the appended claim.

We claim:

A scarf pin fastener comprising a conical shell having a guide hole at its apex and an inward flange at its lower end, a closing plate supported on said flange provided with a central guide hole and an eccentric guide hole, a fixed block disposed in said shell and provided with a longitudinal groove regis tering with said apex guide hole and central guide hole and with a longitudinal recess on one side communicating with said groove, a slide rod extending through said eccentric guide holel provided with a fork at its upper inner end playing in said recess and with a handle at its lower outer end, a rotary clamping roller carried by said fork and projecting into said groove, and a spring disposed on said rod between said fork and ysaid plate and normally operative to lift as our invention, We have signed our names saidk rod and hold said clamping roller in in presence of tWo subscribing Witnesses.
